WHEELED GUN-CARRIAGE.

Specification o'f'Ltters' Patent.

Patented Dec. 30, 1913.

Application filed April 18, 1913. Serial No. 762,107.

To all whom it may concern:

Be it known that I, EMILE BOURDELLES, a resident of Paris and a citizen of France, have invented new and useful Improve ments in Wheeled Gun-Carriages, which are fully set forth in the following specification.

This invention relates to Wheeled gun carriages. j

A wheeled carriage has already been proposed which is constituted by a frame on the small supporting upper carriage for the gun pivots, the said frame itself being pivoted around an axis perpendicular to the longitudinal axis of the axle. In this arrangement the frame was perfectly rigid.

The present invention has for its object to provide a gun carriage comprising the above features but difierentiated therefrom by the fact that the frame is jointed and comprises a base pivoted in the axle and two longitudinal members pivoted to the said base by means of a universal joint while at the same time these members bear upon the axle for example by means of two sleeves.

In order that the said invention may be clearly understood and readily carried into effect, the same will be described more fully with reference to the accompanying drawings in which Figure l is a plan view, partly in broken section, showing a gun carriage embodying my invention; Fig. 2 is a detail sectional view taken on the line AA of Fig. 1; Figs. 3 and 4 are detail. views of locking means for the arms of the frame, Fig. 3 being a sectional view taken on the line BB of Fig. 4.

In Fig. l is shown a gun carriage, on the axle Z) of which is mounted an under carriage h adapted to rotate about a line normal to the axle 6, preferably by means of a pivot 72.; this under carriage receives the central or training pivot g of the small upper carriage supporting the gun, not shown. Mounted on axle Z) by means of sleeves a are two arms a, each of which has a universal joint connection with the under carriage h. This joint connection comprises a rod 7', one end of which is slidable in a socket 7& formed in the side of the under carriage h, the opposite end of which is provided with forks z in which is pivoted a member is having trunnions resting in bearings formed in the side of arm a. The arms a, a with the member it constitute a frame in which the gun with its training mechanism is mounted by means of a training pivot g.

The sleeves a may be smooth. In this manner separated props are formed which are capable of pivoting around the axle b (an arrangement that has already been employed for wheeled carriages of light guns)- Each of the arms a pivoted around the axle can also be locked in various positions according to the exigencies of the ground by employing an efficient clamping device, such as that represented in Figs. 3 and 4, which consists of the sleeve a formed at the extremity of the prop which is internally screw threaded and is screwed onto corresponding threads 6 on the axle b. This sleeve a may be slit radially (Fig. 4) and comprises on each side of the slit a lug a the two lugs can be clamped by means of a bolt and nut c.

The props or branches at of the frame may of course be folding or telescopic if desired.

What I claim and desire to secure by Letters Patent of the United States is 1. In a wheeled gun carriage, the combination of an under carriage having a connection with the axle of said carriage for turning about a line normal to said axle, two arms adapted to serve as props revolubly mounted on said carriage axle, and universal joints connecting said arms with said under carriage and having a slidable connection with one of said members.

2. In a wheeled gun carriage, the combination of an under carriage having a connection with the axle of said carriage for turning about a line normal to said axle, two arms adapted to serve as props revolubly mounted on said carriage axle, universal joints connecting said arms with said under carriage and having a slidable connection with one of said members, and means for locking said arms to said axle.

3. In a Wheeled gun carriage, the combination of an under carriage having a pivoted connection with the axle of said carriage for turning about a line normal to said axle, two arms adapted to serve as specification in the presence of two subprops revolubly mounted on sa d carnage scribing Witnesses. axle, a universal 01nt mounted on each arm and having a slidable connection with said EMILE BOURDELLES' 5 under carriage, and means for locking said Witnesses:

arms to said carriage axle. HENRI MARIE,
